I have a Lenovo P71 laptop with an integrated 720p HD Camera with Microphone. However, the camera doesn't seem to be detected by the system, because when I open video capture software like Cheese, I just get the message "No device found."

I've tried enabling and disabling many items in my kernel's configuration under Device Drivers -> Multimedia Support, but I haven't gotten any results. Does anybody know where I should be investigating or how to solve this problem.
